British and US analysts are appaerntly operating from a secret UFO-hunter HQ in Soho

Although the bulk of the operation deals with the militarisation of space, the search for alien life is still included in the team's brief.

Although the MoD refuses to discuss individual units, Liz Quintana, director of military sciences at the Royal United Services think tank, said: “Britain has maintained its interest in space and the issue of UFOs.

"It would not surprise me if the UK and US had an office here.

“Space is becoming increasingly contested and congested. Some of this is peaceful, some of it has dual use and some distinctly nefarious. Russia and China particularly are active.”
